Method for making heterogenous catalysts

Abstract

A method of making a heterogeneous catalyst, the catalyst produced therefrom, and the use of the catalyst, comprising mixing a dried ion exchange resin with a solution of a ketone and a metal, swelling the ion exchange resin, distributing the metal in the resin, and transforming without reducing agents the metal to zero valent at a temperature below 120° C.

What is claimed is: 
     
       1. A method of making a heterogeneous catalyst comprising:
 mixing a dried ion exchange resin with a solution of a ketone and a metal; 
 swelling the ion exchange resin; 
 distributing the metal in the resin; and 
 transforming without reducing agents the metal to zero valent at a temperature below 120° C. 
 
     
     
       2. The method of  claim 1  wherein the dried ion exchange resin comprises at least one of a dry ion exchange resin and a partially dry ion exchange resin. 
     
     
       3. The method of  claim 1  further comprising:
 removing the ketone from the ion exchange resin. 
 
     
     
       4. The method of  claim 1  further comprising:
 drying a wet ion exchange resin. 
 
     
     
       5. The method of  claim 1  wherein the catalyst comprises 0.1 to 15 percent metal ion, based on dry weight of the catalyst, distributed therein, the metal ion selected from one or more of palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and silver. 
     
     
       6. The method of  claim 1  wherein the ketone comprises acetone. 
     
     
       7. A heterogeneous catalyst made by the method of  claim 1 . 
     
     
       8. A method of making a heterogeneous catalyst comprising:
 mixing a dried ion exchange resin with a solution of a ketone and a metal of at least one of palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and silver; 
 swelling the ion exchange resin; 
 distributing the metal in the resin such that the metal comprises 0.1 to 15% by weight on a dry basis of the catalyst, and 
 transforming without reducing agents the metal to zero valent at a temperature below 120° C.
